Application filed July 28, 1887. SeriaLNo. 245,550. (No model.)

To'all whom it may concern: 7

Be it known that I, ALEXANDER JoNEs, of

Racine, in the county of Racine and State of Wisconsin, have inventedcertain new and useful Improvements in Roofing Fabrics, of

which the following is a specification.

My invention has reference to an improved roofing material; and itconsists in a novel construction of the same, as hereinafter set forth10 and claimed.

In the drawings I have shown a perspective view of the apparatus bymeans of which the roofing material is made; but although I havedescribed the said apparatus in detail herein :5 I reserve to myself theright to make it the subj act-matter of a separate application.

I will first describe the apparatus employed and then the materials andtheir mode of application by means of said apparatus.

A indicates atank or vat, of iron or other suitable "material, beneathwhich is a .fi're-f space, B, preferably provided with a grate uponwhich to place fuel. This tank is desighed to-contain a mixture orpreparation with which to saturate cotton goods or other fabric, ofwhich the roofing material in part consists. Near the bottom of the tankor vat is a bar, 0, which may convenientlybe carried by a frame, D,running in guides inthe 0 ends of the tank or. vat, said bar serving topress down and hold beneath the surface of the contents of chamber theweb or sheet E of fabric to be treated.

F indicates a bar parallel with the bar G,

located at or near the top of the tank or vat A and directly over thesame, said bar serv= ing as a scraper to remove the surplus mate-- rialor composition carried up by the web orfabric from the tank or vat.

G indicates a frame-work exten ing from the rear side of the tankbackward a considerable distance. The portion of the framework next toand immediately in rear of the tank or vat is furnished with aclose-table or 5, platform, H, upon which is placed a body of sand orequivalent material, and the remaining portion of the frame-work isformedwith, longitudinal central and side bars, I, andcross-bars J, thelatter separated from each 0 other, so asto permit the air to passfreely between them. At the rear end of the framethe purpose of drawingthe end of the fabric work G there is placed a box or receptacle, K,

and above and removably mounted in suitable hearings or supports is ashaft or arbor, 1., provided with a handle or wrench by which to turnit.

N indicates a hopper or box to contain sand or like material, andprovided at its bottom with a feed-roller, 0, or equivalent means forcausing a uniform discharge of material from the hopper upon the web orfabric passing beneath it.

P indicates a bar provided with books a, upon which to hook the fabric,and Qindicates a rope or band extending from a bridle, 6, attached tothe ends of the bar P to the shaft or arbor L. This bar 1? and rope orband Q are employed. onlyin beginning the treatment of a bolt or roll offabric, and are for from the tank or vat A to the arbor or shaft L. AWhen this is accomplished, the first'shaft L is removed and a new vonesubstituted. The fabric is unhooked from the bar I and wrapped about theshaft or arbor L; and by turning the latter the material isdrawn forwardand wound into a compact roll as fast as treated.

Motion may be given to the arbor 'L and feed-roll 0 from any convenientsource of power,- or the shaft L may be turned by hand and the roll 0driven by a belt, R, passing about a pulley on said roll, and a secondpulley on the shaft orarbor L, the latter being conveniently formed withor attached to the wrench M, so that it may be removed from one arborand placed on another.

Having now described my apparatus, and with the remark that it may beconsiderably modified as to its general structure, the pre cise form oftank and heater, sanding devices, 8.00., being susceptible of variation,1 will pro oeed to describe the proportions or compounds employed andthe mode of applying them. with the aid of the apparatus abovesetlforth. I first place within the tank or vat Athe followingsubstances or materials in the proportions and usually in the quantitiesstated-z One hundred pounds of rosin, ten pounds of gum-shellac, fivepounds of litharge, twentypouuds of rosin-oil, ten pounds oflinseed-oil, and ten pounds of asp'haltu m. I then startija fire in thespace Bwithin the tank or vat and produceheat snflicient to melt thesesubstances together, stirring and ,mixingthe same to in-. sure a perfectunion thereof, and I maintain a fire beneath the tank or vat whiletreating the fabric to. insure a proper fluidity of the composition anda thorough saturationof the fab ric; I also place upon the bed or tableH and in the hopper N a supply of sand free from sticks, pebbles, orforeign matter of any kind, 4 that upon the bed or platform H beingadvis-r ably rounded up in'th'e middle, so as to insure a-stretchi'ngpfthe fabric over it from edge. to edge anda certainty. of contact ofevery portionof the lower face of the fabric with sand. Having madethese preparations, I provide a belt or roll of woven fabric, preferablystout cotton good s, and I carry one end thereof over the edge of theouter side of tank or vat A, holding the goods firmiyat its sides andpress ingit down into the composition or preparationin the tank or vatby means ofthe crossbarG and its frame D, which should be of sufficientweight to'hold the fabric beneath the surfaceof the solution, but whichshonldnot 25 be sent quite to the bottom of the tank or vat,

as in thatcase there wouldbe danger of scorching tlfefabric orofimpeding its travel through the yat. By this manner of starting thematerial through the vet a portion -of about six or eight inches is leftuncoated, thus enabling. the-attendants to draw the fabric forward overthe bar F and upon the bed or table H with' out selling the hands, aswould otherwise in-' evitab y occur The-un'coated portion, being 5carried upward over the bar F and to the upper side of the bed orplatformH, is hooked upou'the hook'sor teeth a of the bar 1?, and therope or band L attached to said bards theb wound upon the arbor or shaftL by turning the wrench M, thereby drawing forward the bar 1*,Iand withit the fabric E, which, in thus moving forward; travels over the bar Fand has the surplus coating removed from it and thrown back intothe-tank or vat. The saturated-fabric 'passing over the body of sand on*the'table-H becomes thoroughly and evenly coated-with the sand, whichadheres tenacious] y totheifahric, owing to thestickinessof thecomposition, while at the same time the upper s'urfaee is'similarlycoated with sand by reason .of.a discharge of a constantand uniformstream through the enter esd'under the action of the I roller 0, drivenby .the band Rfrom the pul l'ey c of arbor L. As the fabric p fromg-y-the sand-covered table or platform H, it enters upon the open rearportion of the frame G and is exposed to the air above and below,- the aband or rope L being supported by the central :ban, I, and. the bar Pbeing supported by the same and the side bars, as will be readily seen."When. the bar P reaohesthe arbor'L, the fabric is nnhooked from'saidbar, asecond arbor issub' stituted for the first, the unceated end ofthema-L terialiis wrapped upon the fresh arbor, and the winding begins.Any surplus sand] ing upon- -prevents adhesion of the prepared fabricthereto, .andleaving the arbor in condition for immediate reuse when thematerial is taken scope of my invention.

'thenpper face of the fabric falls in o thc'box' K as the fabric windsupon the arbor, and the sand is thereby saved for further use, Theuncoated portionfirst wound upon the arbor therefrdm; The."fra'me.is ofsuch length that the quick drying composition applied to it becomessufiiciently dry. to prevent, with the aid of sand applied to its faces,any adhesion of'the coils upon the shaft L, one to another. Thefabricbeing thus prepared is ready for immediate applicatioi to theroof; but-previous to placing 015831116 upon the roof I prefer to coverthe roof with a layer of tarred felt, tacking the prepared 1 fabric uponthesame with considerably-lapped joints, the two uniting one with theother in a'short time by reason of the cementing action of the coating 8of the felt and of the roof. After the fabric hasbeen applied to theroof it is treated with a preparation consisting of one ehnndred poundsof Cleveland iron-cladpaint or other heady mineral paint, seventy poundsof-lino seed-oil, five poundsof litharge, ten pounds of gum-shellac,andten pounds of American zinc, this preparation being carefully mixedand applied as a paint or coating with a brush, and the surface whilestill freshbeing ca're- .fully coated with a layer of sand to render thesame fireproof, or practically so.

The ingredients and proportions above stated are those which I haveafter long experim'enting determined upon as best; but I do not wish tobe understood as restricting myself to the precise ingredients orpropertions stated, as they maybe modified considerabl-y'withoutdeparting from the spirit and 7 Thus, with regard to the solution asapplied to the fabric in .the

, tank or vat A,I may employ instead of the one. hundredpounds of resinabove mentioned a like quantity of asphaltum, omitting the ten pounds ofasphaltum mentioned, or, in no other words, nsing'only one hundredpounds in all. So, too, the litharge may in some cases beomitted, and amineral oil known to the trade as mineral linseed-oil maybe substitutedfor the rosin-oil, or for therosinoil n and 1inseed-oil. The finalcoating or preparation may also be modified by employing, instead of onehundred pounds of iron clad paint fifty pounds of such paint and fiftypounds of whiting. The linseed-oil may berzo omitted, and the so-calledmineral linseedoil or cotton-seed oil may be substituted. The lithargemay be omitted and the quantity of zinc may be doubled, in'whicb casethe shellac Y may --be omitted. r2 Pu'lvcrized brick or stone may beemployed in lieu of sand, though sand is preferred as.

being cheaper and more easily applied. As

aboyelstated, however, I prefer the ingredicuts. and the'proportionsfirst given. r 0

Anyother means 'of heating maybe employed -as, for instance, a coil or.coils of steam-pipe may be placed in the vat A, or any equivalentwell-known means may be employed for heating the material. in the vat ortank.

Having thus described my invention, what I claim isit 1. Theherein-described roof-covering, consisting of a layer of felt, a layerof cotton fabric saturated with a mixture of rosin, shel- 1o phaltum,coated on both faces with sand, and

a top dressing fo'l' mineral paint-, linseed-oil,

litharge, shellac, and zinc, or the described equivalents of thesematerials, in substantially 1 the proportions ,aboveset forth.

lac, litharge, rosin-oil, linseed-oil, and as- 2. The herein describedroofing material, consisting of woven fabric saturated. with a mixtureof rosin, shellac, litharge, rosin-oil, linseed-oil,and asphaltum, ortheir described equivalents, in substantially the proportions stated,and coated on both faces with sand or its equivalent.

In witness whereof I hereunto set my hand in the presence of twowitnesses.

ALEXANDER JONES.
